Static Screen – Product Description
Product Overview
The DAGYEE static screen is a robust, non-powered solid-liquid separation device designed for wastewater treatment and industrial effluent pretreatment. Constructed entirely from stainless steel, it uses a wedge wire screen to capture suspended solids from water without any moving parts or electricity.
Working Principle
Wastewater flows evenly across the inclined wedge wire screen. Liquid passes through the narrow slots while solids are retained on the screen surface. The captured solids slide down under gravity and hydraulic force, discharging continuously from the lower end.

Table 1: 5-Year Total Cost Breakdown
| Cost Type | What's Included | % of Total (5 Years) |
|---|---|---|
| Purchase Price | Equipment, freight, installation | 30-40% |
| Operating Cost | Electricity, labor, auxiliary equipment | 20-30% |
| Maintenance Cost | Mesh, spare parts, repairs, downtime | 30-40% |
So the real way to save money isn't just beating down the upfront price. It's reducing the other two-thirds too.
Let me give you an example:
Machine A costs $3,000 upfront, but needs $700 in maintenance every year. Over 5 years, total cost is $6,500.
Machine B costs $4,000 upfront, but only needs $150 in maintenance every year. Over 5 years, total cost is $4,750.
The more expensive one actually saves you money. That's why you need to look at the big picture.
Key Features
Engineered for reliability, efficiency, and low maintenance
| Feature | Description |
|---|---|
| No Moving Parts | Zero motors, bearings, or drives. Operates entirely by gravity and hydraulic force. |
| Stainless Steel Construction | Made from SS304 or SS316 for excellent corrosion resistance and long service life. |
| Wedge Wire Screen | Self-cleaning profile wire design prevents blinding and maintains open area. |
| Adjustable Weir | Allows fine-tuning of flow distribution across the screen width. |
| Compact Footprint | Simple, space-saving design requires minimal installation area. |
| Low Head Loss | Requires only 0.5-1.5 meters of gravity head to operate effectively. |
| Easy Maintenance | No lubrication, no belt changes, no moving parts to wear out. |
| Customizable Sizes | Available in various widths and slot openings to match specific flow rates and solids loading. |
Advantages
1. No Energy Costs
Because the static screen has no moving parts and operates by gravity, it consumes zero electricity. For facilities running 24/7, this represents significant annual savings compared to mechanical screens.
2. Virtually Maintenance-Free
With no motors, bearings, or chains to maintain, the static screen requires only periodic visual inspection and occasional cleaning. No lubrication, no belt replacement, no gearbox oil changes.
3. Reliable 24/7 Operation
There are no mechanical components to break down. As long as water flows, the static screen keeps working. This makes it ideal for unattended or remote installations.
4. Self-Cleaning Screen Design
The wedge wire profile creates a continuous shearing action that helps dislodge trapped particles. This self-cleaning effect reduces blinding and maintains consistent hydraulic capacity.
5. Low Installation Cost
With no electrical connections, no control panels, and no moving parts, installation is simple and inexpensive. The unit can be placed over an open channel or flume with minimal civil work.
6. Environmentally Friendly
Zero energy consumption and no chemical additives make the static screen a green technology for solids removal.
7. Handles High Solids Loading
Static screens are particularly effective for applications with high concentrations of fibrous solids — such as paper mill effluent, slaughterhouse wastewater, or textile processing.

| Industrial Pretreatment | Primary solids removal before further treatment |
| Biogas / Digester Feed | Removal of inert solids from organic waste streams |
How to Size a Static Screen
To select the right static screen for your application, you will need:
1.Flow Rate – Peak and average flow (m³/h or GPM)
2.Solids Loading – Concentration and type of solids (fibrous, granular, etc.)
3.Slot Opening – Based on particle size you need to remove
4.Available Head – Height difference between inlet water level and discharge point
5.Channel Width – If installing in an existing channel
Contact DAGYEE with your site parameters, and we will recommend the optimal screen size and configuration.
1. Proven Quality
Every DAGYEE static screen is manufactured from premium stainless steel with precision-engineered wedge wire. Each screen undergoes thorough quality inspection before leaving our factory.
2. Customization
We offer custom widths, slot openings, frame designs, inlet configurations, and mounting options to match your specific channel or application. No two projects are exactly the same — and we don't believe in one-size-fits-all solutions.
3. Fast Delivery
Standard sizes are kept in stock for immediate shipment. Custom orders are manufactured efficiently with typical lead times of 2-4 weeks.
4. Technical Support
Our engineering team assists with sizing, installation guidance, and troubleshooting. We don't just sell equipment — we provide solutions.
5. Factory-Direct Pricing
By manufacturing our own equipment, we eliminate middleman markups. You get high-quality equipment at competitive prices.
Maintenance Guidelines
While the static screen requires far less maintenance than mechanical screens, we recommend:
Simple, low-maintenance routine for long-lasting performance
| Frequency | Action |
|---|---|
| Daily | Visual inspection for excessive solids buildup or bypass |
| Weekly | Hose down screen surface to remove any stubborn debris |
| Monthly | Check for screen damage or wear; verify weir levelness |
| Quarterly | Inspect frame and supports for corrosion (unlikely with SS304/316) |
Maintenance Tip: For fibrous applications, periodic cleaning with a brush may be helpful. Avoid using high-pressure washers directly on the wedge wire at close range, as this can deform the screen profile.
